To all whom it may concern:

'Be it known that l, FRITZ A. ANDERSON,

a citizen 'o'fthe United 'States, residing at Milton, fin the county of Rock and State of lV'isconsin} have invented certain new and useful Improvements in Adapters, of which the followi ng is a specification.

9 This invention relates to adapters.

It will be explained as applied to an adapter :forluse with a therapeutic lamp.

lCherapeutic'lamps are used in thetreatment of various diseases. The lamp attach ,ment which confines and directs'therays upon the 'areaundergoing treatment is com monjly called an applicator. The applicatoris attached to the lamp by 'a device known as an adapter,

An example of a therapeutic lamp with which the herein described adapter inay be Y used is disclosed in my U. 'S. Patent No.

1,435,193, granted November 4, 1-922.

One of [the objects of this invention is to provide an'improved adapter.

Another object is to provide an adapter by means of which applicators mayfbequicktherapeutic purposes.

Another o'bject'is to provide an adapter on V wh ch applicators having orifices of various sizes and shapes can be easily and quickly mounted.

Another object is to provide an adapter from the lamp.

" 7 Other objects and advantages aFtejr appear.

I In general, the adaptor comprises "two readily se 'Ja-rable sections. One section is attachedto thelamp andthe other section'is adapted to carry an applicator. The lampsection is arranged to rotate theapp'licator Y v 1s spread sulfie entlyto permit ring 10 to section to provide for the adjustable posialong line 22 elf- Fig. 1. v

Fig. *5 is an enlarged perspective of a "ratchet pawl which forms a part of the lamp section. 1

The device as illustrated comprises two readily separable sections, a lamp section 5 and an applicator section 6. Lamp section 5 is-adapted for relatively permanent mountin-gon alamp iii-any desired manner. -App'lic'ator section 6 is adapted to carry various forms of ap-plicators and to be readily attached to and detached from the lamp section.

inner ring lO, Ring 10 can be threaded over an-y correspondingly threaded cylindrical has a pair" of parallel knurled flanges '11.

A-plnralityofteeth" 12 are for-med between ;flanges1;1 so as'to provide acireular ratchet Teeth a12-are each divided into two annu larsections by a circumferential groove Ring" 10 is provided with-an inwardly extending ri1n 15'against' whioh a lens 16 may' rest; 'f L'ens I6 is held in position-by ring '17 which is threaded into ring 10 to clamp the "lens again-st rim 1'5. Suitable packing 18 maybe provided to form a watertight joijnt around the lens. Such l a w-atertight joint 'isoften advisab'le when :the adaptfer is used'wit'h a water cooled lam-p.

An outer-member '19, which may be in the iorm or a ring 15 mounted 1n-,qroove1 l.

Outer ring '19 is provided with an outwardly projecting lug 20. A radialcut 21 through the middle of dug 20 permits the 'ends of ring lfil to be spread apart.

In assembling the lamp section; ring 19 be inserted therein Ring 1 9 is then positioned in groove 14 and a cap-22 isthreaded upon lug 20 so asto holdthe 'sametogether. An aperture '23 in 'lug 20- hasa tooth :faced 24 in contact lwithratchet' 13. *Pawl- 24 has a pair 'of-groov'es in its op'posite ends. These groovesZfi-t over ring 19 and prevent rotation of-pawl 24, although allowing the Lamp section 5 has an internally threaded pawl to move longitudinally. A guide pin 28 mounted on the ratchet face of pawl 24 projects into groove 14, so as to hold the pawl in alignment with ratchet 13. The inner diameter of ring 19 is made slightly greater than the diameter of groove 14 so that spring 26 normally holds outer ring 19 eccentric to inner ring on which it is mounted.

The teeth of ratchet 13 engage the teeth of pawl 24 to retain ring 19 in any position to which it may be turned. Ring 19 may be turned, when desired, by exerting suiiicient substantially tangential force on lug 20 to cause pawl 24 to ride over the teeth of ring 10.

A pair of diametrically opposed slots 29 are formed in outer ring-19. These slots may be positioned equidistant from lug 20.

Applicator section 6 has a socket 30 for receiving and holding an applicator. Socket 30 is formed in a cylindrical member 31 which has an outwardly extending annular flange 32. Flange 32 has a lateral rim 33 which is extended to form a pair of projecting lugs 34.

When section 6 is attached to the lamp section of the adapter, rim 33 fits snugly over and encloses the adjacent knurled flange 11 and lugs 34 are positioned within slots 29. In order that lugs 34 may be positioned in slots 29 with rim 33 fitting over the outer periphery of inner ring 10, outer ring 19 must be moved to a concentric position relative to member 10. This is accomplished by a radial thrust on lug 20 sulficient to overcome the pressure of spring 26.

After mounting applicator section 6 on ring 19 and relieving the radial thrust on lug 20, spring 26 moves ring 19 to its normal eccentric position relative to ring 10. The close fit of rim 33 over ring 10 holds the applicator section concentric with ring 10 when ring 19 returns to its normal position. Slots 35 are provided in lugs 34, so that ring 19 in moving to its eccentric position in groove 14 looks lugs 34 within slots 29 and the lamp and applicator sections are secured together.

Cylindrical member 31 has a set screw 36 mounted thereon so that an applicator may be securely fastened within socket 30.

Since applicator section 6 is rotatable about member 10, an applicator fastened to member 31 will be rotated therewith.

Member 31 may be used as an applicator, if desired, by holding the open end thereof against the surface to be treated.

Thus it will be seen that an adapter is provided for mounting on a therapeutic lamp, said adapter having a portion thereof rotatable about the remainder of the adapter and detachably mounted thereon so as to be easily, though not necessarily, removed when mounting applicators on the detachable portion, whereby applicators of various sizes and shapes can be quickly mounted on the lamp and rotated as desired.

Having described my invention what I claim as new and desire to secure by Letters Patent, is 1- 1. An adapter for attaching light applicators to a therapeutic lamp and comprising, a lamp section through which light from the lamp may pass and which has a part for rigid attachment to a lamp and a part rotatable upon the iirst mentioned part, an applicator section through which the light from the lamp may pass to an applicator carried thereby, and a lug and slot connection between the applicator section and the rotatable part of the lamp section whereby the same may be locked together and readily separated.
